Magnetic and electric field fluctuations in the Pc 1 frequency range (0.2-5 Hz) have been observed by the polar-orbiting Viking satellite. The fluctuations, interpreted here as electromagnetic ion cyclotron (EMIC) waves, were observed during 21 of 450 orbits surveyed between 0900 and 1400 MLT, near 3 R{sub E} geocentric altitude, and at invariant latitudes from 59{degree} to 77{degree}. The frequency structure of the waves is investigated, using spectral analysis and by determining the… CONTINUE READING
